Synthesis and characterization of CdS nanorods in ionic liquids [BMIM][BF_4]

Keywords： ionic liquids , solvent , cadmium sulphide , nanorods

以室温离子液体1-甲基-3-丁基咪唑四氟硼酸盐为介质制备了CdS纳米棒,采用X射线衍射和透射电镜对样品进行了结构表征。结果表明所制备CdS纳米棒具有六方相结构,直径为30nm左右,长度为300nm左右。离子液体和长链烷胺的双重作用促使了CdS一维棒状结构的形成。离子液体同时起到了修饰剂和导向剂的作用。

CdS nanorods were synthesized in room temperature ionic liquid via chemical reduction under ambient conditions.XRD and TEM were used to characterize the structure of the CdS nanorods.The results indicate that the diameter and the length of the bone-like nanorods are about 30 and 300nm respectively and the structure of the CdS nanorods were hexagonal phase.The one dimension CdS nanorods weie formed by dual role of ionic liquids and decylamine.So we conclude that the room temperature ionic liquid is not only used as reaction medium but also as finishing agent and guiding agent.
